Fotoluminescência dos compostos (Ba1-xSrx)MoO4 sintetizados com diferentes solventes
(Universidade Federal de São Carlos, 2013-10-15)
The molybdates with scheelite-type tetragonal structure is a family of inorganic materials that has received considerable attention since the discovery of their luminescent properties, with emission in the visible spectral ...
Obtenção de estruturas de nanocompósitos poliméricos híbridos condutores
(Universidade Federal de São Carlos, 2013-03-28)
In this work, hybrid electrical conductive nanocomposites structures with potential to be applied in conductive and electrostatic dissipative devices were obtained. Such structures were produced by combining two types of ...
Utilização de alumínio recoberto por aspersão térmica em tubulação de condensadores evaporativos
(Universidade Federal de São Carlos, 2013-12-16)
In evaporative condenser production, galvanized steel has become the most suitable material for piping system production, since it has high corrosion resistance and relative low commercial value. With proper surface ...
